ELECTRIC-CURRENT REGULATOR.

SPECIFICATION forming part of Letters Application filed fln 14:, 1838.

To all whom, it may concern.-

Be it known that I, JOSEPH WILHELMUs BALET, of the city, county, andState of New York, have invented a new and lmproved Electric-CurrentRegulator, of which the folcally the motor used in connection. with theregulator. Fig. 3 is a plan view showing how the electrical connectionsin a system are Similar letters and figures of reference indieatecorresponding parts in both views.

The, object of my invention is to provide a simple and efficientcurrent-regulatorlfor use in connection with any electrical circuit, butmore particularly designed for use in connec-; tion withstorage-batteries. w 1

My invention consists in a translatingde vice formed of a helix and apair of soft-iron bars supported movably in the helix, each bar beingconnected with a switch arm adapted to move between a pair of contactsconnected with the circuit in which the helix is placed.

It also consists in the combination,with the translating device, of anelectric motor having its field-magnet connected with the main circuit,so thatthe current may always flow in the same direction through theconductor of the field-magnet, and having commutatorbrushes connectedwith the contact-points of the translating device, so that the currentmay be sent in either direction through the armature of the motor, andthus enable the motor to be used for operating switches in one directionor the other according to the requirements of the current beingregulated, all as hereinafter more fully described.

The connections shown in Fig. 2 are intended for very heavycurrents. InFig. 3 the connections are made in parallel with the lamps 21. I do,however, not limit myself to any connection, while same is made so as tosatisfy the circumstances. The main difierence between the twoconnections shown is Patent .N'o. 398,927, dated March 5, 1889.'Se'rialNo. 273.841. (No model.)

that in Fig. 2 the object is to get a'constant electro-motive force, andin Fig. 3 to get a constanLpotent-ial.

Upon the spool A, which is preferably of -e1liptical form, is wound aquantity of wire forming a helix, B. In the center ofthe said spool Aare supported frames formed of the bars a. a aid the arms I), 1),connecting the lower ends of the said bars, and the switch-v armse'o',connecting the upper ends of the said bars and projecting over the faceof the spool A. The bars a. and a as well as the arms b b c c, are ofnon-magnetic material, while the bars a a are of soft iron. The arms-b bc c are pivoted above 'and below the spool A upon pivotal screws e,extending through brackets -f, attached to the top and bottom of thespool A.

Upon the upper head, g, of the spool-A are secured six binding-posts, 12 3 4 5 6. To the bindingposts 5 6 are attached flat springs 12.

. lhflwhich bear upon the outer sides of the arms 01c, and the-saidsprings and arms are oppositely arranged with respect to each other, thearm 0 projecting between the bindingposts 1 2, and the arm 0' projectingbetween the binding-posts 3 4. The bindingrposts 1 2 3 l are providedwith contactscrews 1', arranged in the paths of the said arms.

Arranged in this way the bars a a are sup- 8o ported parallel with eachother within the centerof the helix B, so that when a current is sentthrough the helix the bars are similarly magnetized and consequentlyrepel each other. The repulsion of the bars a. a is opposed by thesprings h h, so that when the currentpassing through the helix producesa repulsion between the bars a 0. which is equivalent to the pressure ofthe springs h h, the arms 0 0' will take a central position between the0 cont-aet screws 2'. When the current diminishes, the springs carry thearms 0 0 over toward the contact-screws'i of the binding-posts.

. 2 4. When the strength of the current increases, the repulsion of thebars a a moves the arms a 0' so that they are brought into contact withthe screws '11 of the posts 1 3 against the pressure of the springs h h.

The motor 0, used in connection with my device, is of well-knownconstruction, having the field-magnet and the armature 7c revolvingbetween its poles, the current being supplied to the armature throughthe commutator-brushes Z l. The field-magnet j of the motor 0 isconnected with the main-circuit conductorD in the shunt. Thebinding-post 1 of the translating device is connected directly with thecommutator-brush Z of the motor. The binding-post2 is connected with thebrush Z of the motor, "and the bindingpost 3 is connected with thecommutator-. The binding-posts 4 is connected brush l. with the brush Z,and 'binding-iposts 5 land -6 are connected with the main conductor D ina shunt around the field-magnet of the motor C; One terminal of thehelix B is conn'ectedwi'ththe main conductor outside of one-of theconnections of "the fi'eld jnrfagnet and binding-post 6.Theother-terniinal is coiinectedwiflithe m'ain conductorwithin \Vhen"the current "flows in the directionihdi- 7 cate'd bythe arrow throughthe anain tondn'ct'or,"-ai-portion of it*pass'es'tlirongh thehe g lhxBanctnfagnetizesthetars'a a horeorless,
